Abstract: Abstract Multiple observations have shown that widespread oceanic anoxia may have played an important role in the end-Permian mass extinction and delayed biotic recovery in the Early Triassic. However, it has not been reached a… read more here.

Abstract: Abstract Widespread oceanic anoxia has been implicated as a killing mechanism during the end-Permian mass extinction (EPME). A high-resolution investigation of pyrite framboids and bioturbation structures in the Shangsi section of South China has revealed… read more here.

Abstract: Abstract The latest Permian extinction (252 Myr ago) was the most severe in the geologic record. On land, widespread Late Permian gymnosperm/seed-fern dominated forests appear to have suffered rapid and almost complete destruction, as evidenced by… read more here.

DOI: 10.1130/g38487.1
Abstract: Sedimentary records from the northwest margin of Pangea and the Tethys show anomalously high Hg levels at the latest Permian extinction boundary. Background δ 202 Hg values are consistent with normal marine conditions but exhibit… read more here.
